Astrophysicist Daniele Sorini, one of the scientists who pondered this paradox, thinks that the answer to this question may be hidden in the multiverse. The paper, prepared by Sorini and his team at Durham University, was recently published in the journal Monthly Notices of the Royal Astronomical Society. According to this article, we cannot see aliens because they are not in our universe.
According to Sorini and his team, who argue that the theory of multiverses should be integrated into equations such as the Drake equation, there may be universes in the multiverse that are much more suitable for life than ours. Therefore, we need to consider the possibility that the life forms we expect to see based on probability calculations may have emerged in these universes.
The research, which focuses specifically on the dark energy density in the universe, argues that a universe with a dark energy density that will allow 27 percent of the matter it contains to turn into stars will be more conducive to the emergence of new life forms. In our universe, this rate is 23 percent. Therefore, according to Sorini, our universe is one of the universes where the probability of the emergence of life forms is relatively lower.
Sorini thinks this possibility could offer an answer to the Drake equation. But there will be many people who will object to him on this issue. Because the Drake equation shows that, considering the conditions that currently exist in our universe and the Sun-like stars, more life forms should have emerged under current conditions. According to observations made by space telescopes, there are 40 billion Earth-like planets in habitable zones around Sun-like stars. And that’s just the ones in the Milky Way Galaxy.
